GEARING FOR OPERATING STRAW-CUTTERS, CHOP-GRINDERS, AND CORN-SHELLERS.

SPECIFICATION forming part of Letters Patent No. 344,363, dated June 291886. Application filed December 5, 1885. Serial No. 184,847. (Nomodel.)

To all whom it may concern.-

Be it known that I, J AMES WV. EMENHIsER, a citizen of the UnitedStates, residing at Berne, in the county of Adams and State of Indiana,have invented a new and useful Improvement in Gearing for OperatingStraw- Cutters and Corn-Shellers and Chop-Grinders, of which thefollowing is aspecification, refer ence being had to the accompanyingdrawings.

My invention has relation to improvements in gearing for operatingcombined straw-cutters, chopgrinders, and corn-shellers; and the noveltyconsists in the peculiar construction and combination of parts,substantially as hereinafter fully set forth, and specifically pointedout in the claims.

In the accompanying drawings, Figure 1 is a side elevation of myimproved machine. Fig.

2 is a plan view. Fig. 3 is a vertical longitudinal section on the linemm of Fig. 2. Fig. 4 is a vertical cross-section on the line y y of Fig.1, taken through the straw-cutting de vices. Fig. 5 is an enlargeddetailed view, partly in rear elevation and partly in section, of thedriving-shaft-operating mechanism and the supporting-frame. Fig. 6 is adetail view of one of the gear-wheels of the driving-shaft mechanism,and Fig. 7 is a vertical sectional view thereof on the line 3 3 of Fig.6.

Referring to the accompanying drawings, in which like letters ofreference indicate corresponding parts in the several figures, A designates the main frame of a combined strawcutting, chop grinding, and cornshelling machine,which comprises a horizontal section, A, and a verticalsection, A the latter arranged at right angles and at one end of theformer and secured thereto in any suitable manner.

The horizontal section A of the main frame comprises longitudinal sidebars, a, and crossbars a, and is supported at a suitable height from theground by legs (6 and the vertical section A" of said main frameconsists of vertical longitudinal side bars, a connected at their upperends by a cross-bar, a, and braced near their lower ends by a similarcrossbar, (6".

B designates the operatinglever of the machine; O, the reciprocatingrack-bar; D E, the train of driving-gear, and G the driving-shaft, thelatter extending longitudinally of the horiin a slotted or cut-awayportion, 1), of one of 6 the side bars of the vertical section A of themain frame.

B designates a coiled retracting-spring secured at one end to the uppercross-bar of the frame A and at its opposite end to the upper end of thereciprocating rack-bar O at the point, and by the same pin or bolt thatpivots the operating-lever B thereto. The lower end of the reciprocatingrack-bar has a weight, B secured thereto or suspended therefrom, whichis of sufficient ponderosity to overcome the retractile force of thespring B, and thus maintain or hold the reciprocating rack-bar in astate of equilibrium and render its operation eas I attach importance toequalizing the reciprocating rack-bar and to the pivotedoperating-lever, as by such construction the machine can be operatedwith the greatest ease and with a minimum expenditure of power, theweight and retracting-spring opposing each other to an equal degree, andholding the re ciprocating rack-bar under tension and ready forimmediate action at all times.

The driving gear-wheels l) E are mounted on pins or bolts d, which bearin parallel crossbars at one end of the horizontal frame A, and saidgearwheels are arranged on opposite sides of the reciprocating rack-bar,and are driven thereby in opposite directions or planes, as indicated bythe arrows in Fig. 7. Each of the gear-wheels comprises disks or wheelsD D the former of which is made solid and provided on its vertical faceadjacent its fellow disk D with an outwardly-projecting hub or disk, d,of smaller diameter than the wheel D, and the wheel D is made open likea ring, the diameter of which is equal to the diameter of the disk orhub d of the wheel D, over which it is fitted and adapted torotatetherewith, under circumstances which will be presently explained. Thedisk 01 is cut away or notched in its periphery,as at (1 and receives anelastic packing, (P, and a pawl, d*, which are loosely fitted thereinand prevented from rotating with the wheel D which .it is designed tooperate, by means of retaining-shoulders and the frictional contactofthe surfaces. In lieu of the elastic packing and loose pawl, the pawlmay be pivoted and normally pressed outward beyond the periphery of thediskd, in which it is seated, by a spring, as is obvious.

The inner periphery of the wheel D is ser-. rated or provided with aseriesof. teeth, ad, with which the pawl isadaptedto engage to rotatethe same, according to the direction or plane of rotation ofthegear-wheel D The inner vertical face of the disk'd of the wheel Dfits flush with the inner face of the ringwheel D", and aclamping-plate, E is fitted against the said inner faces of the disk dand wheel D to secure them together, while permitting the wheel D torotate freely thereon under some circumstances, the. plate E beingrigidly secured to the disk d vby screws or bolts 6 v The drive-wheels DE have their respective wheels D D facing each or lying in the-sametransverse plane in the frame A, the wheels D in engagement with theteeth of the rack-bar G, and the wheels D meshing with a pinion, q,,oninner end of thedriving-shaft G, said shaft being journaled in properboxes or bearings g, secured to the horizontal frame'A, and extendinglongitudinally thereofat or near its middle. When the reciprocatingrack-bar descends, the loosely-mounted wheels D Dof the gearwheels D Eare rotated in oppositedirections, the loose wheel of the gear-wheel Dengaging the pawl of the wheel D",.and thus drives the pinion g of thedriving-shaft, the loose wheel of the drive-wheel E loosely revolvingaround the disk or hub d of its-wheel D and the teeth d thereof slippingover the end -0f the retainingpawl. When the reciprocating rackbar isdrawn upward by the operating-lever, the reverse action of thedrive-wheels D E takes place, the wheel D" of the drive-wheel Drevolving loosely around its hub-dandthe wheel D remaining idle, and thewheel D of the drive-wheel E engaging its retaining-pawl and operatingto drive the wheel D thereof, and to revolve the pinion g ofthedriving-shaft in the same plane of a rotation thatthe drivewheel Drevolves it. The drive-wheels D E are thus alternately operated torotate the driving-shaft by the downwardand upward strokes of theequalized reciprocating rackbar,and the saiddriving-shaft is rotated atall times in the same direction or plane.

I do not desire in this application to claim any of thehereinafterdescribed mechanisms for shelling corn, cutting straw, and:grinding chop, as the invention in the present instance is confined tomy peculiar gear mechanisms for rotating the driving shaft that operatessaid hereinbefore-mentioned mechanisms.

The straw-cutting mechanism H comprises the disks H, secured on thedriving-shaft and carrying the knives, and a table, H on which the strawis placed and fed to the cuttingdisks between two rollers, I I, one ofwhich isgeared to and rotated by motion transmitted from thedriving-shaft through the gearwheels 13 t", which are suitablysupported.

The chop grinding mechanism K preferably consists of a toothed cylinder,k, that is rigidly mounted on the driving-shaft G, and

the concaves L are arranged around the cylinder and have the usualteeth, and they are inclosedwithin a case, M, that is provided with theproper ingress and discharge open ings.

The corn-sheller mechanism, N,shown herein preferably consists of thetoothed cylinder vN .anda series of toothed bars, 0, which are (suitablyheld in place on proper heads and arranged within. an inclosing'case, P,having the usual ingress and discharge openings A balance-wheel, Q, isrigidly secured on the "driving-shaft to steady the motion thereof andof the several mechanisms operated thereby.

The operation of, my invention is obvious from the foregoingdescription, taken in connection with the drawings.

Itwill thus be seen that I provide a machine which: can be used for avariety of purposes, eitherone .or more of the mechanisms being adaptedfor use either separately or simultaneously; that the machine can beoperated with great ease and withaminimum expenditure of power,'-owingto the fact that the reciprocating rack-bar is equalized and held undertension, and that the machine is simple, strong, and durable i n itsconstruction, thoroughly effective in operation and, can be successfullyoperated by one pe'rson,the feeding-table of the straw-cutter andhoppers of. chop-grinder and corn-sheller being in convenient reach ,ofthe-attendant standing. at the, operating-lever. The lower end of thereciprocating rack-bar is provided at its ends with stop-lugs s, whichlimit the upward movementthereof, and the slat c of said rack-bar, hasplane edges, and in its reciprocating movements it bears against thesmooth or plane peripheries of the disks E of the drivegear-wheels D E,and is thus guided in its movement and kept in its proper position tocause the teeth thereof to engage or mesh with the drive gear-wheels D Eproperly. Thelower. cross-bar of the vertical section A of the mainframe'is slotted or cut away i to provide a passage forthe equalizedreciprocating bar, and serves as a guide thereto to 1 prevent-lateralmovement or play of the upper end when acted on by the operating-lever.

I do not desire to limit myself to the precise construction andproportions of parts shown and described,as I am aware that many changestherein may be made without departing from the principle or sacrificingthe advantages of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination ofa frame, an operatinglever pivoted therein, areciprocating rack-bar connected to said lever and carrying a weight atits lower end, a retracting'spring connected to the upper end of therack-bar and the frame, a drivingshaft, and intermediate drive-gearwheels meshing with the rack-bar and driveshaft, and successivelyrotated to drive the driving-shaft, substantially as described.

2. In combination with areciprocating rackbar and a driving-shaft,intermediate drivewheels which are rotated in opposite planes andsuccessively brought into operation to rotate the driving-shaft, eachdrive-wheel having a gear-wheel provided with a hub carrying a pawl, anda loose gear-wheel mounted on said hub and having teeth on itsinnerperiphery to engage the pawl when the drive-wheel revolves thedriving-shaft, substantially as described.

3. In combination with a driving-shaft and a reciprocating rack-barhaving a plane edge, intermediate drive-Wheels comprising a gearwheelhaving a hub of smaller diameter and carrying a spring-pawl, agear-wheel loosely mounted on the hub and having teeth on its innerperiphery to engage the pawl, and a clamping-disk secured to the hub ofone of the gear-wheels and having its periphery bearing against theplane edge of the rackbar, sub stantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
